humans have 23 pairs of chromosomes for a total of 46 chromosomes the last pair is the sex chromosome so the sex chromosome is its own chromosome. the sex chromosome decides witch gender a person is. and everybody starts out female the way you become male is if a y shows up.
Sex cells have half the number of chromosomes as the original cell, and are said to be haploid. In human sex cells there are 23 chromosomes.
23 pairs
A female human has two X sex chromosomes in her cells. A male human has one X and one Y sex chromosome in his cells.
XX
Each human skin cell has 46 chromosomes, which are organized into 23 pairs. This includes one set of 23 chromosomes inherited from the mother and another set of 23 chromosomes inherited from the father.

There are 23 haploid chromosomes in a normal human gamete (sex cell).
There are 23 haploid chromosomes in a normal human gamete (sex cell).
as in gametes? per human there is around 24
A female human has two X sex chromosomes in her cells. A male human has one X and one Y sex chromosome in his cells.
Sex cells, called gametes, are different to other cells in that they contain half the number of chromosomes. So in a human sex cell, there are 23 chromosomes, whereas a normal human cell has 46 chromosomes.
a human, gametes have 23. half the number of other cells
All non-mutated somatic (non-sex cell) cells have the same chromasomes and same genes, within an organism. The difference between the cells is which of the genes are active in it.
